Allows you to define how sound is directed to devices. There are two 

modes to select: Classic and Multi-Stream.

■

Classic mode - Emulates the behavior of Microsoft Windows XP, where 

sound is heard either on the speakers or on the headphones, but not 

both at the same time. To select Classic mode, click on the 

corresponding icon. 

■

Multi-Stream - Different sounds can be played on speakers and 

headphones simultaneously. To select Multi-Stream mode, click on the 

corresponding icon.

Two "Play" buttons allow you to play separate sounds in both modes:

■

When the red Play button is pressed, a sample sound is played on the 

headphones.  

■

 When the blue Play button is pressed, a different sample sound is 

played on the speakers. 

In Classic mode, if the headphones are plugged in, both red and blue 

sounds are heard from the headphones and if they are unplugged, both red 

and blue sounds are heard from the speakers. 
In Multi-Stream mode, the red sound is only played on the headphones 

and the blue sound is only played on the speakers.

On this page allow you to customize your listening experience by selecting 

different profiles for headphones and speakers.
The smart equalizer (EQ) has five presets that automatically enhance the 

sound quality of music or voice communications. The preset options 

include: Jazz, Dance, Concert, Classical, and Voice. Each preset has been 

optimized for the fullest sound experience. For example, the Classical 

preset emphasizes the middle range of notes while the Dance preset 

emphasizes the bass end of notes. Selected devices and profiles are 

denoted by highlighted icons.
